United States naval bases in the Philippines
The United States Navy held a number of bases in the Philippines Islands in the Pacific Ocean. Most were built by the US Navy Seabees, Naval Construction Battalions, during World War II. The US Naval Bases in Philippines were lost to the Empire of Japan in December 1941 during the Philippines campaign of 1941–1942.
